To alliuhom it may] concern:

' Be it known that I, JosErH A. SALZMAN, a citizen of the United States,residing at T ledo, in the county of Tama and State of Iowa,haveinvented new and useful Improvements in Seat-Controlled Closets, ofwhich the following is a specification.

This invention relates generallyto an improvement in toilets of thatclass known as seat controlled wherein the flushing operation is carriedoutby'the weightof a person. -The main object of the "present inventionis the provision'of a seat controlled toilet I i in which the flush tanki's-normally empty weight'of the-person, the pressure-of the and isopened to the supply pipe by the water entering thesupplytank serving.to

close the outlet between said tank and the .bowl-whichoutlet is openedupon the relief of the pressure through the automatic 010s ing of thetank against the supply pipe by relieving the toilet of the weight ofthe person. a

A further object of the invention is the utilization of an auxiliaryfeed pipe for directing the water supply into the bowl at times duringthe communication of the sup- N ply pipe and tank.

, The invention in its preferred form of detailswill be described in thefollowing specification, reference being had to the accom panyingdrawings, in which Figure l 's a perspective View illustratingtheautomatic toilet complete. Fig. 2 is an enlarged vertical' -sectionalView through Fig. 1. Fig.3 is a bottom plan of the seat. Fig. 4 is anenlarged broken elevation showing particularly the seat operation of theReferring particularly to the accompanying drawings, the improvedautomatic toilet includes a bowl 1 which, aside from the de-- tails ofconstruction hereinafter described,

may be of any preferred form of construction; For cooperation with thebowl I employ a tank 2 which although in its general form may be of anyshape or size, though by reason of'the peculiar constructionof theoperating parts is to be understood that the flush tank is preferably ofless capacity than the usual tank, thereby permitting it to be lessconspicuous and more ornamental 7 than usual.

above or in'line with the trap therein, the inner end of. the auxiliaryfeed pipe being preferably, though not-necessarily, provided.

with-a spray or cylinder 1 A-valve10is arranged in cooperation with 1the seat 6 having a flat. or pressure face 11 next the'water supply pipe3,isaid valve, when .openbeing arranged within the enlargement to permitthewater to freely flow around the same. IA stem 12 is connected to thevalve 10,,said stem extending through the pipe 5 and through an opening13 formed in and through an oflset'l l: of the bowl proper, the upperend of the stem being provided with any suitableform of pres- I surehead 15--for' a purpose which will later appear. Above the feed pipe 7the pipe 5 is interiorly closed against the upward passage of the,water, being suitably packed to permit movement of the stemltherethrough while preventing the passage of the water. i In the tankisnarranged an approximately semi-cylindrical valve seat 16communicating with the flush pipe 17-which leads from the tank andinto-the bowl in proper flushing relation to the latter, the usualguiding or spreading meansv for the water within the tankbeing employedtoproperly direct the flush. A stand pipeyl8 is arranged within thetank, mounted if preferred in suitable guides to permit alverticalmovement of said pipe, the lower end of the stand pipe being formed orprovided with. a valve 19 designed to cooperatewith the seat l6. Aspring 20 is arranged tofnormally maintain the stand pipe elevated, thatis with. the valve 19 off the seat .17, providingfree'communication' ibetween the flush pipe 17 and the tank. While preferring the spring 20to normally maintain the valve 19 open itis obvious that othermechanical means may be employed to this end, and by the term spring Icontemplate any equivalent structure which will normally maintain thevalve open.

i The feed pipe 7 leads to and through the bottom of the tank and withinthe same to a point near the upper end being laterally projected andformed with a downturned delivery section 21 which opens at its free endwithin the stand pipe and slightly spaced from the closed bottomthereof. A bell 23 is arranged to encircle the stand pipe, said bellhaving a diameter exceeding that of the stand pipe with its closed upperend embracing the delivery section of the feed pipe and its lower openend terminating some dis tance below the upper open end of the standpipe. A pipe Qatis secured within the tank being closed at the lower endand opened at the other end,'said pipe being formed at its lower endwith a comparatively minute pipe connection 25 which leads into thetank, as shown. i I

To provide for securing the toilet seat and lid to the bowl in a mannerto permit a proper operation of the seat in the toilet uses and preventsuch operation ofthe seat when the lid in closed position, is used foran ordinary seat or support, I secure the parts of the bowl by apeculiar hinge arrangement; In this arrangement, I secure uprights 26 tothe bowl in the'usual manner, and pivot the seat; proper 27 thereto by aU-shaped member 28, the cross bar 29 of which is rotatably connected tothe seat by straps 29, and the arms 30 have lateral terminals 31 to seatin openings in the uprights. The rear end of the seat proper, which mayhave a slight projection, will thus overlie the pressure head 15 of thestem 12 of the valve. The cover or lid proper, shown at 32, is hinged tothe uprights above the connection of the seat thereto, the hingeconnection 33 being of any appropriate type which will permanentlysupport the rear end of the lid or cover to prevent pressure of the sameon the seat, so that when the seat and cover are in closed positions anypressur'e upon the lid will not transmit movement to the seat to operatethe valve.

In the use of the device, the weight of the person will depress the seatwith the effect to engage the pressure head 15 of the valve steam andopen the valve. The water from the supply pipe 3 will now pass aroundthe valve and to the feed pipe 7 a portion, however, of such waterpassing through the pipe 8 to wash the sides of the bowl. The waterleading through the supply pipe 7 is delivered into the stand pipe andby the initial pressure will seat the valve 19 against its seat 16 andof course against the pressure of the spring 20. The water continuing toflow in the stand pipe will rise above the same and flow downwardlybetween the stand pipe and below and into the tank, the downwardmovement of the water tending to further maintain the stand pipe invalveseating position, as will be obvious. The flow of the watercontinues during the occupancy of the seat or until the tank iscompletely filled. Prior to the complete filling of the tank the pipe 24is filled. Upon relief of the pressure on the seat, the valve 10 closesand the pressure of the supply is cut off. The spring 20 regainscontrol, the valve 19 is opened and the water in the tank flushes thebowl. After the flushing operation, which, owing to the size of theflush pipe, is rapidly performed, the water remaining in the pipe 24will trickle down into the'bowl and supply the same'with suflicientwater to reestablish the trap.

It will thus be seen that the toilet is automatic in its operation, thatwhen the same is not in use the tank is filled during the occupancy ofthe seat and emptied for the flush ing operation immediately thereafter;that during the use of the toilet a stream is continually directed intothe bowl and that the flushing operation of the bowl is not per mitteduntil the relief of the tank from the pressure of the supply.

What is claimedis:

1. The combination with a bowl and flush tank, of a supply pipe, meansnormally closing said tank against the supply pipe, weight-operatedmeans to establish communication between the supply pipe and tank, andan auxiliary feed pipe establishing direct communication between thesupply pipe and bowl subsequent to the operation of said means. i

2. The combination with a bowl having a trap and a flush tank, of asupply pipe, a valve normally closing the tank against said supply pipe,and an auxiliary feed pipe in communication with the supply pipe betweenthe valve and tank, said auxiliary feed pipe opening within the bowlabove the trap.

In testimony whereof I afiiX my signature in presence of two witnesses.
